Abstract

Claims (51)

1. Non-transitory computer-readable media comprising instructions that, when executed, configure processing circuitry of a computing system to:

receive data indicative of a declarative testing descriptor for active testing of a virtualized service;

obtain, from an orchestration layer, metadata associated with the virtualized service, wherein the metadata specifies a unique name for the virtualized service within a namespace of a cluster managed by the orchestration layer;

provide a label in a custom resource that defines an input of a test agent, wherein the label is defined as an object within the metadata;

determine, using the declarative testing descriptor and the metadata, an active testing configuration for an instance of the virtualized service by matching the test agent to the virtualized service based on matching the label against objects within the cluster;

and

determine service level violations for the instance of the virtualized service based on a result of the test agent sending active test packets according to the active testing configuration.

2. The non-transitory computer-readable media of claim 1 , wherein the active testing configuration includes placement of the test agent.

3. The non-transitory computer-readable media of claim 1 , wherein the instructions configure the processing circuitry to provide the active testing configuration to a control center that orchestrates the test agent sending active test packets, wherein the control center instantiates the test agent and one or more monitoring services based on the active testing configuration.

4. The non-transitory computer-readable media of claim 1 , wherein to obtain the metadata, the instructions configure the processing circuitry to:

listen for one or more events defined by the customer resource;

identify an event of the one or more events; and

obtain the metadata based on the identified event.

5. The non-transitory computer-readable media of claim 1 , wherein the test agent comprises a virtual test agent, and wherein the instructions further configure the processing circuitry to deploy the virtual test agent inside a sidecar container to send active test packets.

6. The non-transitory computer-readable media of claim 1 , wherein the instructions further configure the processing circuitry to measure, based on the test agent sending active test packets, service performance between nodes.

7. The non-transitory computer-readable media of claim 1 , wherein the virtualized service comprises a first virtualized service, and wherein the instructions further configure the processing circuitry to create a second virtualized service to enable performance testing of the first virtualized service.

8. The non-transitory computer-readable media of claim 1 , wherein the instructions further configure the processing circuitry to:

deploy the test agent outside the cluster; and

test outbound virtualized services with the test agent.

9. The non-transitory computer-readable media of claim 1 , wherein the instruction further configure the processing circuitry to:

receive, from the orchestration layer, updated metadata indicating a change to a cluster associated with the virtualized service;

determine, by the computing system, updated active testing configuration using the declarative testing descriptor and the updated metadata; and

update, by the computing system, placement of the test agent according to the updated active testing configuration.

10. The non-transitory computer-readable media of claim 1 , wherein the computing system is part of an edge cloud system.

11. The non-transitory computer-readable media of claim 1 , wherein the virtualized service comprises a containerized service.

12. A computing system comprising:

one or more processors; and

memory accessible to the one or more processors, wherein the memory stores instructions that, when executed by one or more processors cause the one or more processors to:

receive data indicative of a declarative testing descriptor for active testing of a virtualized service;

obtain, from an orchestration layer, metadata associated with the virtualized service, wherein the metadata specifies a unique name for the virtualized service within a namespace of a cluster managed by the orchestration layer;

provide a label in a custom resource that defines an input of a test agent, wherein the label is defined as an object within the metadata;

determine, using the declarative testing descriptor and the metadata, an active testing configuration for an instance of the virtualized service by matching the test agent to the virtualized service based on matching the label against objects within the cluster; and

determine service level violations for the instance of the virtualized service based on a result of the test agent sending active test packets according to the active testing configuration.

13. The computing system of claim 12 , wherein the instructions cause the one or more processors to provide the active testing configuration to a control center that orchestrates the test agent sending the active test packets, wherein the control center instantiates the test agent and one or more monitoring services based on the active testing configuration.

14. The computing system of claim 12 , wherein to obtain the metadata, the instructions cause the one or more processors to:

listen for one or more events defined by the customer resource;

identify an event of the one or more events; and

obtain the metadata based on the identified event.

15. The computing system of claim 12 , wherein the test agent comprises a virtual test agent, and wherein the instructions further cause the one or more processors to deploy the virtual test agent inside a sidecar container to send active test packets.

16. The computing system of claim 12 , wherein the virtualized service comprises a first virtualized service, and wherein the instructions further cause the one or more processors to create a second virtualized service to enable performance testing of the first virtualized service.

17. The computing system of claim 12 , wherein the instructions further cause the one or more processors to:

deploy the test agent outside the cluster; and

test outbound virtualized services with the test agent.

18. A method comprising:

receiving, by a computing system, data indicative of a declarative testing descriptor for active testing of a virtualized service;

obtaining, by the computing system and from an orchestration layer, metadata associated with the virtualized service, wherein the metadata specifies a unique name for the virtualized service within a namespace of a cluster managed by the orchestration layer;

providing a label in a custom resource that defines an input of a test agent, wherein the label is defined as an object within the metadata;

determining, using the declarative testing descriptor and the metadata, an active testing configuration for an instance of the virtualized service by matching the test agent to the virtualized service based on matching the label against objects within the cluster; and

determining service level violations for the instance of the virtualized service based on a result of the test agent sending active test packets according to the active testing configuration.

19. The method of claim 18 , wherein the active testing configuration comprises one or more test agent Internet Protocol (IP) addresses, test agent tag, service endpoints, template names and parameters.

20. The method of claim 18 , wherein the test agent comprises a virtual test agent, the method further comprising deploying the test agent within the cluster to send active test packets.
